In this paper, the detection scheme of the spatial coordinates based on stereo camera for a intelligent path planning of an automatic mobile robot is proposed. In the proposed system, face area of a moving person is detected from a left image among the stereo image pairs by using the YCbCr color model and its center coordinates are computed by using the centroid method and then using these data, the stereo camera embedded on the mobile robot can be controlled for tracking the moving target in real-time. Moreover, using the disparity mad obtained from the left and right images captured by the tracking-controlled stereo camera system and the perspective transformation between a 3-D scene. and an image plane, depth information can be detected. Finally, based-on the analysis of these calculated coordinates, a mobile robot system is derived as a intelligent path planning and a estimation.

소아의 경우 의사소통이 불완전하므로 자신의 건강 상태를 정확히 표현할 능력이 없거나 떨어진다. 따라서 소아에 대한 의학적 판단에 기초한 기술적 방법의 제시가 필요하다. 이를 위해 본 논문에서는 소아 건강 상태를 측정할 수 있는 한방 4대 진단 방법 중에서 망진을 이용하여 소아 질환 진단기기를 개발하고자 한다. 특히 호흡과 관련된 중요 인체 부위로 폐 질환에 대한 망진기기를 개발하기 위한 방법을 제안하고자 한다. 이를 위해 본 논문에서는 소아 얼굴을 입력 받아 얼굴 영역에 대한 분할을 하고 폐장과 관련된 명당 부위를 추출한다. 추출한 소아 영상에서 색상 분석을 행하여 객관적이며 시각적인 데이터를 가지고 소아 폐질환 진단기기를 개발하고자 한다. 최종적으로 소아 폐질환자와 정상인의 비교, 분석을 통해 제안한 방법의 유용성을 입증하고자 한다.

현대 사회는 다양한 사회적 생활과 활동을 통해서 에너지를 소비하는 형태이기에 이로 인한 스트레스 등을 해결하기 위해 매운 음식을 선호하는 사람들이 증가하고 있다. 따라서 본 논문에서는 매운 음식을 섭취했을 경우, 사람의 체질에 따라 얼굴의 주요 영역에 대한 색상 변화를 측정하고 이를 비교, 분석하는 실험을 수행하였다. 이를 위해 체질감별 설문 검사지를 통해 피실험자를 체질에 따라 5명씩 구성하였으며 매운 음식을 섭취하기 전과 후의 얼굴 영상을 수집하였다. 수집된 얼굴 영상을 입력 신호로 받아 Lab 색체계를 적용하여 붉은색의 정도를 수치 값으로 표현해주는 a*값의 변화를 비교 분석하는 연구를 수행하였다.

AAM(Active Appearance Model) is an algorithm to extract face feature points with statistical models of shape and texture information based on PCA(Principal Component Analysis). This method is widely used for face recognition, face modeling and expression recognition. However, the detection performance of AAM algorithm is sensitive to initial value and the AAM method has the problem that detection error is increased when an input image is quite different from training data. Especially, the algorithm shows high accuracy in case of closed lips but the detection error is increased in case of opened lips and deformed lips according to the facial expression of user. To solve these problems, we propose the improved AAM algorithm using lip feature points which is extracted based on a new lip detection algorithm. In this paper, we select a searching region based on the face feature points which are detected by AAM algorithm. And lip corner points are extracted by using Canny edge detection and histogram projection method in the selected searching region. Then, lip region is accurately detected by combining color and edge information of lip in the searching region which is adjusted based on the position of the detected lip corners. Based on that, the accuracy and processing speed of lip detection are improved. Experimental results showed that the RMS(Root Mean Square) error of the proposed method was reduced as much as 4.21 pixels compared to that only using AAM algorithm.

In this paper, hand acupuncture used as a way of life medicine in everyday life, the influence of human organ will be investigated by applying IT techniques. For this, hand acupuncture is based on priority of the most important organ in the human body to target the cardiac associated with cardiac reflex point A16 acupuncture point before and after for 5 min to stimulation of facial images were collected and applied to the Lab color system associated with the cardiac, color value of cheonjung and lips region were measured for comparison and analysis. Finally, by measuring the change in bio-image signals A16 acupuncture point stimulation effects on cardiac function were performed to investigate the effectiveness of acupuncture. Also, statistical significance tests from the experimental results were performed whether the experimental results is valid or not.

Four volumes of the script of the Avatamska Sutra written with golden paste on dark blue papers manufactured in Koryo Dynasty which are collected or deposited in every museum of Japan show specific features on their cover paintings. In general 3 or 4 lotus flowers are wound by arabesque patterns in zigzag on the cover paintings of Koryo scripts, whereas 10 lotus flowers painted with golden paste on the 4 volumes of these scripts are same in their style. Though there is no prayer sentences in 4 volumes of the script, it is possible to know that they should belong to a set of 80 Avatamska Sutra by the results of above studies. In this study the contents of Byunsangwha of the script of 4 volumes of the Avatamska Sutra were discussed at first and their manufactured era should be postulated by the results of style analysis of cover paintings and Byunsangwha. First thing that saint hair of Buddha was painted with cobalt color is same as that of Byunsangwha of Munsuchoisangsungmusenggebueob prayed in Tejeong 3rd year, king Chungsuk 13th year(AD 1326). Second thing that the beads in topknot of saint hair and lips were painted completely with pink color, and ears, face outline as well as bosom outline disclosed through monk's cloth were also painted with pink color, furthermore the last thing is that Buddha's face was coated with golden paste. All of these things are same as shown in the characteristics of Byunsangwha of the scripts of Kanezawa Daishoji, Matsue Tenrinji and Haga Tera collection in Japan. However, since the cloud pattern style of Byunsangwha of the script is similar to that of the Byunsangwha manufactured in reinstatement era of king Chungsuk, it is possible to say that these 4 volumes of script should be manufactured in the reinstatement era of king Chungsuk.

In this paper, an algorithm for anchor frame detection in news video is proposed, which consists of four steps. In the first step, the cumulative histogram method is used to detect shot boundaries in order to segment a news video into video shots. In the second step, skin color information is used to detect face regions in each shot boundary. In the third step, color information of upper body regions is used to extract anchor object, which produces candidate anchor frames. Then, from the candidate anchor frames, a graph-theoretic cluster analysis algorithm is utilized to classify the news video into anchor-person frames and non-anchor frames. Experiment results have shown the effectiveness of the proposed algorithm.

We report the HST pixel analysis results of the interacting face-on spiral galaxy, NGC 5194 (M51), which is the first step of a new observational research project, PANCluG (Pixel Analysis of Nearby Cluster Galaxies). We derive several quantities describing the pixel color-magnitude diagram (pCMD) of NGC 5194, suitable for future comparisons with the pCMDs of other galaxies. We investigate the spatial distribution of pixel stellar populations, finding that the spiral arm pattern and the tidal interaction with NGC 5195 significantly affect the stellar populations in NGC 5194. We find that the pixels corresponding to the central active galactic nucleus (AGN) of NGC 5194 show a very tight sequence in the bright-end of the pCMD, of which spatial distribution seems to agree with the AGN torus region.

In this study, researcher intended to extract the major factors of makeup design from Yangju-beolsandaenori-tal(masks) and Songpa-sandaenori-tal which have been handed down to the present among many kinds of the Korean folk masks, and to apply those factors to the modernization of traditional culture in terms of makeup design. The 17 Sandaenori-tals exhibited at 'The special exhibition of the Korean folk masks' in 1981 by the national folk museum of Korea were selected as the objects of this research. The formational analysis in terms of shape, color and material was conducted. The 5 factors of this analysis are as follows; face and hair, forehead, eye and eyebrows, mouth and nose. The beauty expressed in Sandaenori-tal includes naturalness, eccentricity and good-humor. The human feelings are expressed candidly and simply through naturalness. The eccentricity in Sandaenori-tal overemphasizes the shape of mask unsymmetrically. And it is expressed ghostliy in black, white and red colors. The good-humors in aesthetic viewpoint was expressed in surprised faces and innocent smile. Researcher applies the good humour to the art makeup in strong natural colors and shapes.
